CHARLES BREARLEY MOORE, 0F EVANSTON, ILLINOIS, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO AMERICAN .ARCH COMPANY, OF NEW` YORK, N. Y., A CORPORATION O F NEW YORK.

Application led September 23, 1908.

T0 all whom t may concern Be it known that I, CnAnLns BREARLEY MOORE, a citizen of the United States, and resident of Evanston, Cook county, Illinois, have invented a certain new, useful, and Improved Locomotive-Boiler VFurnace, of which the following is a full, true, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in locomotive boiler furnaces and has particular reference to improvements in'arches and arch structures for locomotive fireboxes.

The object of my invention is to provide a simple, economical land efficient arch struc ture for locomotive reboxes.

My invention consists generally' in a locomotive boiler furnace of the construction and combination of parts hereinafter described and particularly pointed out in the appended claim.

The invention will be more readily understood by lreference to the accompanying drawings forming a part of this specification and in which;

Figure 1 is a vertical, longitudinal section of a locomotive boiler furnace embodying .my invention; Fig. 2 is a similar view illus` trating a modification of the invention.

The chief olice of an arch in a locomotive firebox is to prevent the direct flow of the irebox Agases from the grate to the lues and by defiecting or diverting the gases to cause the thorough admixture thereof with the air which enters through the grate or otherwise.

A locomotive firebox, as shown in the drawings, comprises the side sheets, 2, a rear sheet, 3, a flue sheet, 4, and a crown. sheet, 5. 6 represents the irebox grate; 7 the fines leading from the flue sheet, et, and 8 the iue door. The principal members or elements of my novel arc'h or gas mixing partition, as illustrated in Fig. 1, are the transverse members, a. These are regularly spaced apart in the rebox and extend from side to side thereof. I prefer that the elements, a, shall be of Z form in cross section.

They are made of refractory material, such as lire clay, which is capable of withstanding Specilcatlon of Letters Patent.

members, a, and thus the body of gas is thoroughly admixed and with a suiiicient supply of air,.substantially perfect combustion is insured. The members, a, may spring or arch from slde to side of the furnace, or may be supported upon arch tubes, 9, as

shown in the drawings. At the lower end ofk the arch I prefer to close the Vopenings or passages by means of horizontal bricks or slabs, c, laid upon the flanges'of the members, a. This latter construction, if desired, may be extended to the top of the arch by connecting several members, a, by horizontal bricks or slabs, c-c, as illustrated in Fig. 2. l/Vherethis construction is carried out, the arch is provided with an irregular undersurface and a plurality of gas mixing pockets, d, which materially assist4 in preparing the rebox gases for final combustlon. In using an arch of the construction shown in Fig. 2, I prefer to add thereto one or more air heating and introducing sections, e. The sides of the irebox are providedlwith air tubes, which communicate with the channels of the sections, e, and air thus admitted is heatedV will readily suggest themselves to one skilled. I

in the art` Ldo not confine the invention to the specific constructions herein shown and described.

Having thus described my invention, I

claim as new and desire to secure by Letters' Patent A locomotive fire box having a flue sheet the lower 'portion of the Hue sheet, said refractory members being substantially vertical and huvmg substantlaly horlzontal extending portlons, the sald 'refractory members'being adapted to deeet, bale und thoroughlyedn'x the gases sng from the fuel bed before 'they 'pass mit@ the ues, substenbully as cescrlbed,
